Many thanks for your thoughts on this Stewart.
I hear what your saying on the chain seeking a better angle.
I mentioned the chain drops off on the 1st and 2nd cog, but
assume you didn't read the whole post. rather long I know.
I bit the bullet and took off the rear derailleur and bent it back about 3-5mm
as it didn't look aligned when on the 2nd cog.
I wanted to bend it even more but didn't want to force a worse situation.
also, wanted to post a pic, but results wouldn't justify the angle.
Upon completing reassembly
it got a gear better. I can back pedal on the 2nd cog, but not the first.
I don't really care about back pedaling. just doing this to assess situation btw.
Skewers are not true also. Any recommendations on a strong model?
FINALLY, upon reassembling the R. DER. I noticed my cable housing was TOO long,
so this can be the culprit as you mentioned. need to test this out on the next ride
as I'm eliminating a few criteria's at a time.
STAY TUNED for updates.
